Moon Phase Illustration 18928491 Vector Art At Vecteezy If i'm reading this correctly, it has the proper voltage at the pump and it also has a brand new pump since i already replaced it preemptively. also, if i understand correctly, the initial 12v is to "charge the system" with fuel so that there is pressure to fire up. Check the 12v feed from the fuel pump relay to the fuel pump. have you tried a jumper wire from the battery directly to the fuel pump to see if it will solve the problem?.

Moon Phase Illustration 18928494 Vector Art At Vecteezy If you were to put a 1.0 ohm resistor in a fuel pump circuit, it would lower the 13.25 volts prior to 9.78 volts. this is a voltage drop of almost 4.0 volts. the loss of 4.0 volts may not affect the idle of a vehicle, as the fuel pressure may be within specifications. The problem i'm having is that the fuel pump is only getting 6.5 v. i have the batteries on a trickle charger now, but they tested fine, and the fuel pumps (both that were in the vehicle, and my spare) run perfectly when shorted directly to the battery. The fuel pump voltage is a crucial parameter that ensures the proper functioning of the fuel injection system in vehicles. it refers to the electrical potential difference applied to the fuel pump to power its operation. Most modern fuel pumps are designed to operate efficiently at a standard voltage of 12 volts. in general, automotive electrical systems deliver between 12 to 14 volts to accommodate all necessary components optimally.

Most modern fuel pumps are designed to operate efficiently at a standard voltage of 12 volts. in general, automotive electrical systems deliver between 12 to 14 volts to accommodate all necessary components optimally. When the engine is running there is a constant 12 volts to the fuel pump. bump the key to the start position and immediate back to on and the fuel pump will run a 20 25 second cycle. If the relay is not energized, you may read 5 volts at these points as the computer uses a lower voltage to test integrity of the fuel pump circuit when it is not energized. I replaced the fuel pump and then measured the current draw 6.5 7 amps. not much different than the original one. and sure enough the relay gets too hot to handle after driving for 10 minutes. You should have 12 volts at the dark green yellow wire at the fuel pump relay. the inertial fuel shutoff switch is between the relay and the fuel pump. the pink black wire from the inertial switch to the fuel pump should have 12 volts. you can measure the voltage, on the pink black wire, at the fuel pump. here’s the wiring diagram.
